COTTON-GIN.

SPEC ICATION forming part of'Letters Patent No. 331,729, dated December 1, 1885,

Application filed July 14, 1885. Serial No. 171,610. (No model.)

To aZZ whom it may concern Be it known that we, JOHN TYLER NIXON and DANIEL NICHOLAS Gauss, both of Lexington, in the county of Holmes and State of Mississippi, have invented certain new and useful Improvements in Cotton-Gins, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure I is a side elevation, partly in section, of a part of a cottingin to which our improvement has been applied. Fig. 2- is a sectional plan view of the same, taken through the broken line as m, Fig. I. Fig. 3 is a plan view of one end of the brush-shaft, and showing a journal-box in section.

Our invention relates to improvements in cotton'gins; and it consists in the peculiar construction and arrangement of parts, all as hereinafter fully described, and pointed out in the claims.

A represents the frame of a cottongin.

B are the ginsaws, and O is the saw-shaft, which revolves in bearings attached to the frame A in the ordinary manner.- To one end of the saw-shaft G are attached a fast pulley, D, and a loose pulley, E, to receive a driving-belt from a steam-engine or other suitable power.

F is the brush to remove the lint from the saws B, and G is the brushshaft. To the journals of the brush-shaft G are attached, or

upon them are formed, V-shaped collars H, which revolve in correspondingly shaped grooves in the journal-boxes I, to hold the brush-shaft G and the brush F from longitudi nal movement. Upon the opposite sides of the journal-boxes I, and at an angle of about forty-five degrees (45) with the horizontal plane of the gin, are formed gudgeons J ,which oscillate in bearings K in the bearing-blocks L, so as to allow the journal-boxes I to rock, and thus prevent the journals of the brushshaft from binding in their bearings should the said brush-shaft spring. The bases of the bearingblocks L slide in grooves in plates M, attached to side bars of the frame A. To the outer ends of the bearing-blocks Lare attached the inner ends of rods N, which pass through holes in the posts of the frame A, and have screw-threads upon their outer ends to receive the nuts 0, so that the inward movement of the bearing-blocks L can be regulated and limited by adjusting the said nuts 0. Upon the screw-rods N are placed spiral springs P, the outer ends of which rest against the inner sides of the posts of the frame A, and their inner ends rest against shoulders, collars, or nuts Q, formed upon or attached to the said rods N, or against the outer ends of the bearting-blocks L.

To the end parts of the brush-shaft G are attached small friction-wheels R, the faces of which bear against the faces of the large friction-wheels S, attached to the saw-shaft C, so that the brush will be driven from the sawshaft by friction.

With this construction there are no belts to slip and burn out, so that the brush will be driven at a uniform velocity, and can be driven up to its full speed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

I. In a cotton-gin, the combination, with the frame A and the saw-shaft 0, provided with the large friction-wheels S, of the brushshaft G, provided with the small frictionwheels R, the bearingblocks L, the screws N,

.nuts 0, and springs P, substantially as herein shown and described.

2. In a cotton-gin, the combination, with the frame A and the journals of the brushshaft G, having V-shaped collars H, of the grooved j carnal-boxes I, having gudgeons J, the bearing-blocks L, having gudgeon-bearings K, the screw-rods N, nuts 0, and spiral springs P, substantially as herein shown and described, whereby the inward movement of the bearing-blocks can be limited and the brush-shaft can spring without binding in its bearings, as set forth.
